1'' all whom it may mncerm lie it known that I. Tnoni's ll. KAXR. a citizen of the l'nited States. and a resident of Youngstown. in the county of Maholr ing and State of Ohio. have invented a new and liuprored EXpanding-l'laehine,of which the following is a specification.

This lllYtllUOll relates to mechanism for sheathing. and other structural material, and its uhject is to provide a machine which shall he simple and powerful. and in which the operations ran he aeeurately controlled.

To the caps s of (:U'lt pair of leanings is atta hed a guide plate 12 to hold the teeth of the rack-l ars in engagement with the teeth of the pinions.

On one end of this shaft 9 is secured a gear H which meshes with a pinion 15 on the shaft 16. which shaft may he journaled in the pedestals 17. Any desirahle rerersin z mechanism may be employed to drive this shaft. such as the welllmowu slow-running clutch-pullers 1S and 19 driver. in opposite directions and loose on the shaft lt. which may engage. the

The machine illustrated in the accompanying drawings is constructed as follows.

Cross heams or 'ays 1 rest on legs 2 and are conn cted by the lnrad-hlocl; or f nine 3":-

follmw. The head-hlock 3 and tail-hlo li 4 are hollow and similarh ron trurted o that. hut one need he des rihed. the llt'zttll)llu'l heing chosen. Mounted in ll ontcr l'aec ia shaft 24 having, an p rating device such as a hand-whe l 2.3 on i'.- outeizend and lit-"(El pinions .Zt' serured to it at. proper intervals. levoluhle in the upper plate 2? of the head-block are a series of vertical shafts 9 sere\\'-threaded at their upper end and lower ends to mesh with the pinions it on the shaft 24-. Collars fit) hold the shaft- 2Q positioned. The openings through the upper late 27 of the head-hloek. through which these shafts ext nd. are slightly larger than the shafts to permit some swinging 'having bevel pinious 29 secured to their all) -movement. Mounted on this plate 27 are lugs 32 which receive the ivots 33 of the levers 34. In the outer biiiircated ends of these lovers are mounted pins 3."), screwthreaded to receive the screw-threaded upper ends of the shafts 28. Connected to the inner ends of these levers is a jaw-bar 36 which is adapted to grip one edge of the metal to be expanded. Secured to the headblock below this jaw-bar is an angle-bar 37 which forms a shelf upon which the metal to be expanded may rest, and against which the edge of the metal is held by the jaw-bar. The shape of the aw will, of course. depend upon the type of metal to be expanded. that shown being adapted for ribbed-mctal-lath.

\Vhere the ribbed-metaLl-ath, shown in the Kane patent referred to, is to be expanded still further, it is desirab e to provide means to hold the ribs parallel to each other. This may he done by mounting guide rods -10 in the jaw-bars 36 as shown in Figs. 5 and G. The holes through the jaw-bars are suitieiently large to permit a slight movement of the rods up and down. On the e reds are sleeves 41 which carry longitudinally extending plates 42, to which are attached the angles 43 which engage the ribs of the metallath.

For expanding the ribbed -metal-lath shown in the Kane patent, the devices shown in Figs. 5 and 6 aredesirable. A sheet -15 of metal may be secured to one angle bar 37 and rest on the other to support the reticulated metal. Small angle bars -16 may be secured to the larger bars 37 in order to furnish ridges that may project into the outer ribs of the ribbed-metal so to insure a strong grip.

The operation of the machine is as follows. The jaw bars being elevated, a sheet 01' slitted metal is slipped endwisc onto the table formed by the angle bars 3?, and the shafts 24 are turned to bring the jaw bars 36 down onto the slitted metal. The driving clutch is then thrown into operation and the tailblock 4 will slowly move back, expanding the slitted metal. When the desired expansion has been attained, the clutch is thrown out of engagement, the tail-block stopping, and the shafts :34 are turned back to lift the 5 jaw-bars. The relea ed expanded metal is removed and the shaft 9' is turned in the opposite direction in bring the tail-block to original posltlon. 1

ll will be understood that the anglebars 3? may be replaced by others of greater or less width, according to the material to be expanded; that jaw-bars of any desired configuration may be employed; that the numher of guides 43 may be varied and that the guides and their supporting rods Manley be entirely omitted.

Many changes may be made in the details of this machine b skilled metal-workers without departing rom the spirit of my invention.

Having now explained my construction, what I claim as my invention and desire to secure by Letters Patent is 1. in an expanding machine, the combination of relatively movable ja\v-carriers, horizontal plates carried thereby to receive the article to be expanded, vertically movable jaws to engage the edges of the article, and laterally movable guiding devices to control the movement of intermediate portions of the article.

2. In an expanding machine, the combination of relatively movable jaw-carrying blocks, a shaft mounted in each block, levers mounted on each block, jaws mounted on the inner ends of the levers, manually operated means engaging the outer ends of the levers to move the jaws up and down, plates projecting from the blocks to support. the article to be expanded, transverse rods extending through the jaws, and guiding devices mounted on the rods.

In an expanding machine, the combination of vertically movable jaws mounted for lateral horizontal movement relative to each other, supporting plates below the jaws,

rods extending across between the jaws,

sleeves mounted on the rods. and guide members extending parallel to the jaws mounted on the sleeves.

4. In an expanding-machine for sheetmetal, the combination of fixed and horizontally movable sets of jaws, bars extending between the two sets of jaws, and guide members for intermediate portions of the SlN'll metal, mounted on said bars.

5. In an expanding machine for sheet metal. the combination of a fixed and a laterally movable jaw carrier, a series of levers pivotally mounted intermediate their ends on each jaw carrier, jaws at the inner ends of the levers, screws engaging the outer ends of the lovers, and means for simultaneously actuating all the screws and levers of a jaw carrier.

6. in an expandingmachine for ribbed shoelaaclal. the c mbination of fixed and movable sets of j ws in longitudinal rows, one set of jaws being mounted for lateral movenu-nt. bars extending between the sets ot'jaws. and longitudinally extendingguides, adapted to engage the ribs of the sheet metal, mounted on said bars.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
